how long does your bottle last you?

i have a 10 pound bottle spraying a 100 shot and just curious how long i should expect it to last me? how many sprays i mean on avg since i know each spray is for a diff length of time. any responses would be great, thanks.

.8 LB per 10 seconds at 100 shot.

You should get about 3 quarter mile passes out of that (on a 100 shot).
